POLISHlNG-IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 707,819, dated August 26, 1902.

Application filed May 16,1902. Serial No. 107,653. (No model.)

T all whom it 11mg/ concern:

Be itkn own that we, JOHN WILSON BROWN, Jr., and HERBERT W. YEAGER, citizens of the United States, and residents of Philadelphia, Pennsylvania, have invented certain Improvements in Polishing-lvlachines, of which the following is a specification.

Our invention relates to certain improvements in machines for polishing or butfmg 1o the edges of sad-irons and like articles.

The Object of our invention is to so construct the machine that a number of sad-ironsV 1. Fig. 1I is a sectional plan View on the line 4. 4., Fig. 1. Fig. 5 is a sectional plan view on the line 5 5, Fig. 1; and Fig. 6 is a view showing the clutch mechanism for engaging the sad-iron.

A is the base of the machine. Mounted on this base is a carriage B, supported in the present instance on a series of rollers a, as clearly shown by dotted lines in Fig. l, and on this carriage is a slide B', having stand- 3 5 ards b, carrying at their upper ends the bearings h for the shaft C. On the shaft is a step-pulley C and on the outer end of the shaft is a bufng-wheel C2, made up of a series of sheets of fabric held together by 4o means of the clamp-plates c c, mounted on the shafts C.

B2 is an adjusting-screw having its bearings in a bracket b2 at one end and arranged to pass through a nut on the slide B. By

turning this hand-wheel the slide can be adjusted on the carriage, so as to adjust the bufing-wheel toward and from the Work.

D is a lever pivoted at d to the frame of the l machine and connected by a link d' at one end to a stud on the carriage B. The other 5o end of the lever is provided with a roller d2, which is actuated by a cam ou a part of the machine, so as to move the carriage, and consequently the buing-wheel, to accommodate irregular work.

d3 is a weight attached to a chain d4, connected to the outer end of the carriage B, and this chain passes around the Wheel d, mounted in bearings in the base A of the machine, so that the tendency of the weight is 6o to move the carriage away from the work; but it is drawn toward the work by the mechanism actuating the leverD, described above.

XVe will now describe the carrier for holding the sad-irons and the mechanism connected therewith.

A is a bracket extending in the present instance from one corner of the base A, and mounted in this bracket is a iixed standard E. The lower portion of the standard is ta- 7o pered to fit the tapered socket a2 in the bracket, and the standard is held in place by a nut e. v

Mounted between the head e on the upper end of the standard E and a bearing e2 on the 75 bracket A is a carrying-frame F. This carrying-frame has channels ff for the reception of bearing-balls, which are mounted between the carryingframe and the portions e e2, as indicated in Fig. l.

G is ashaft having its bearings in a bracket A and having a driving-wheel g to receive a belt from vany suitable power-shaft. On the shaft Gis a worm g,which meshes witha Wormwheel h on a stud H, projecting from the bracket A', and secured to hub of this worm- Wheel 7L is the disk I of a star-Wheel lock-gear. (Shown clearly in Fig. 5.) On an extension of this disk is a pin t', which Works in radial slots c" in the star-wheel I,'secured to the 9o lower portion of the carrier F, so that on each revolution of the disk I the star-wheel and the carrier in the present instance will be moved one-fifth of a revolution. In the present instance there are five spindles J, mounted in bearings f2 of the carrier F, and by having a wheel Zon a hollow shaft L mounted in the head F', secured to a projection F2 of the carrier F. On the end of the shaft L is pivoted a clutch member Z, which is arranged to engage the cross-bar of the sad-iron, as clearly shown in Fig. 6. A rod Z2 extends through the shaft L, being connected at one end to the clutch member Z', and has a collar Z3 at the other end. Resting in a groove in this collar is one arm of a releasing-lever Z4, Fig. 3, pivoted to the head F', so that on depressing the long arm of this lever the clutch can be withdrawn to free the sad-iron. A spring back of the clutch will tend to return the.

clutch to its original position when the lever is released, so that a sad-iron to be 'ground can be simply forced into place/the same as in the ordinary detachable-handle sad-iron. The construction of this clutch will vary according to the style or the design of the iron, and if another object is to be ground it will be made to couple properly to the object.

It will be seen that when the carrier is brought into position and the edge of the iron is in line with the buffing-Wheel, as shown in Fig. 2, the shaft K will slowly drive the spindle J, which will in turn drive the shaft L and turn the iron on edge, so that the entire edge will come in contact with the buftingsurface. In order to allow for the irregularity of the said iron a cam M is secured on each spindle J, and this cam acts against a roller d2 on the lever I), described above. This cam as the spindle revolves Will move the carriage B and the bufiing-wheel toward and from the Work, according to the cut of the cam, so that the buffing-Wheel will always have a ixed relation to the sad-iron or other article to be polished. The cams and the lever are clearly shown in Fig. 4.

The operation of the machine is as follows: When the parts are in operative position, the irons are clutched to the several heads, as shown,and motion is imparted to the machine. The star gear-wheel moves the carrier, so as to bring one of the spindles in line with the buffing-wheel, when it will be locked in this position until during a certain portion of the revolution of its driving-shaft, and during this time the spindle Jris driven slowly and motionis imparted to the sad-iron, so as to present its entire edge to the action of the batting-Wheel. The cam M on the spindle Will move the bufIing-wheel toward and from the Work as the Work is rotated. Thus the buding-wheel will always bear the same relation to the work. After the bufiing-wheel has completed its work the carrier is moved one-fifth of a revolution by the star-Wheel, moving the polished iron to one side and moving into position one that is to be polished. The operator simply removes the polished iron and places another in its stead, and the work is thus continued without interruption.
